SPECIFICATION forming part of Letters Patent No. 402,172, dated April30, 1889. Apploation ii1ed November 23, 1888- Serial No. 291,673 (Nomodel.)

T0 (LZZ wh0m it may concern.-

Be t known that I, DE S010 LOVEJOY, a citizen of the United States,residing at Mescow, in the county o Polk and State of Texas, haveinvented new and useful Iniprovements in Motors, of which the followingis a specificaton.

My inventon relates to mprovements in motors; and it consists in certainnovel features, hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a Sde view of a motorembodying my inven tion. Fig. 2 is 2b front view of the same.

Referring to the drawings oy letter, A designates a chair of the usualor any pre In the seat a of the chair, at the center of the same, I forma guide-opening, B, through which passes & vertica1 post or bar, 0,having l rest 01 secondary seat, D, secured 0 its upper end. The saidseatD is provided on its under side with the depending gudes E, whichproject downward through suitable openings in the seat a of theehair,and thereby secure a true vertical movement of the rest and thebar 0. A spring, F, is coiled around the upper portion of the bar 0,between the ehar-seztt and the rest D, to return the said rest to itsnorma1 position after having been depressed. If so desired, additionalsprings may be placed around the guides Eto aid the spring F inreturning the said rest to its norma1position.

G designates a transverse shaft, journaled in suitable bearingssecuredto the legs of the chair and having mounted thereon, in front of the bar0, a drum, H. This drum H is provided with a transvetrse opening, I,

through which passes a portion of t oord, J, the man part of seid oordbeing coi1ed around the said drum, as shown. F101n its coiled portionthis cord extends rearward across the lower end of the bar 0, fitting ina notch, K, therein,and thence extends upward to a transverseperforation, L, in the said bar, neen; its upper end, and thence throughsad perforation, and downward again through the drum. 1he cord is drawnteut around the bar 0 and the drum, so that when the said bar is beinglowered the oord The drum is provided a t one end with &

ratchet-wheel, M, and on the shaft G, adjacent to said ratchet-wheel, ismounted a gearwheel, N, to the side of which is pivoted a paw1, 0,adapted to engage the ratchetwhee1 M, and held normally in engagementWith smid ratchet-wheel by & spring, P, having one end securedto theside of the wheel N and its other end hearing on the paw1, as c1earlyshoWn.

In operation the operator sits upon the platform 01 rest D, 01 placesaweight thereon, thereby depressing the same against the spring F,thereby ca using the bar 0 to descend and rotate the drum so as to setthe gear-wheekN in m0tion and thereby operette the machinery to whichthe said gear-wheel is geared. When the rest D has reached the lowestlimit of its movement, the Weght is removed therefrom, and the spring Fthen returns it to its former e1evated positon, thereby raisng the bar 0and rotating the drum in the opposite direetion, 2tnd winding the oordthereon, so that upon the next downward movement of the bar 0 the drumwill be again rotated to operate the gearwhee1. It will be observedthatthe pawl is so arranged. as to allow the teeth of the wheel M 130 slippast when the bar C is being raised, so that the gear-wheel N will notbe driven backward. pon the downward movemet of the said bar, however,the ratchetwheel engages the pawl so as to operztte the machinerydriven.

It will be observed chat my device is very simp1e, is co1nposed of fewparts, and the said parts are compactly arranged. The de vice isespecially adapted for running light machines-snob as sewing-machins,churns, and fans-end its advantages are thonght to be obvious.

Having thus described my invention, what I claim and desre to securebyLetters Patent, 1s-

The combination of the chair, the recipro cating bar, the shaft mountedin the 1owcr porton of the chair, the drum 011 sad shaft, the c01dcoilod around the drum and connccted t o the bar, the rest secured tothe upper end of the bar, and the spring coiled around the said ba1between the chair-seat and the rest, as specified.

In testimony that I claim the foregong 21S my 0W11 I have hereto affixedmy sgnature in presence of two witnesses.

DE SOTO LOVEJOY.
